I'm not sure this is the right forum, but hopefully you guys can submit this as a feature enhancement.
Our installation really big and very complicated. We are adding XML comments into the code which is a hassle because if you don't add it inside the exact right XML element, InstallBuilder will strip it out.
We would like to request that every action inside of InstallBuilder have a tab called Comments. This is where as a developer, we can explain the action and why we are doing it.
It would go a long way in documenting our installation for other developers.
